## Usage
### Docker Hub
When authenticating to [Docker Hub](https://hub.docker.com) with GitHub Actions,
use a [personal access token](https://docs.docker.com/docker-hub/access-tokens/).
Don't use your account password.
```yaml
name: ci
on:
push:
branches: main
jobs:
login:
runs-on: ubuntu-latest
steps:
-
name: Login to Docker Hub
uses: docker/login-action@v3
with:
username: ${{ vars.DOCKERHUB_USERNAME }}
password: ${{ secrets.DOCKERHUB_TOKEN }}
```
### GitHub Container Registry
To authenticate to the [GitHub Container Registry](https://docs.github.com/en/packages/working-with-a-github-packages-registry/working-with-the-container-registry),
use the [`GITHUB_TOKEN`](https://docs.github.com/en/actions/reference/authentication-in-a-workflow)
secret.
```yaml
name: ci
on:
push:
branches: main
jobs:
login:
runs-on: ubuntu-latest
steps:
-
name: Login to GitHub Container Registry
uses: docker/login-action@v3
with:
registry: ghcr.io
username: ${{ github.actor }}
password: ${{ secrets.GITHUB_TOKEN }}
```
You may need to [manage write and read access of GitHub Actions](https://docs.github.com/en/packages/managing-github-packages-using-github-actions-workflows/publishing-and-installing-a-package-with-github-actions#upgrading-a-workflow-that-accesses-ghcrio)
for repositories in the container settings.
You can also use a [personal access token (PAT)](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token)
with the [appropriate scopes](https://docs.github.com/en/packages/getting-started-with-github-container-registry/migrating-to-github-container-registry-for-docker-images#authenticating-with-the-container-registry).
### GitLab
```yaml
name: ci
on:
push:
branches: main
jobs:
login:
runs-on: ubuntu-latest
steps:
-
name: Login to GitLab
uses: docker/login-action@v3
with:
registry: registry.gitlab.com
username: ${{ vars.GITLAB_USERNAME }}
password: ${{ secrets.GITLAB_PASSWORD }}
```
If you have [Two-Factor Authentication](https://gitlab.com/help/user/profile/account/two_factor_authentication)
enabled, use a [Personal Access Token](https://gitlab.com/help/user/profile/personal_access_tokens)
instead of a password.
### Azure Container Registry (ACR)
[Create a service principal](https://docs.microsoft.com/en-us/azure/container-registry/container-registry-auth-service-principal#create-a-service-principal)
with access to your container registry through the [Azure CLI](https://docs.microsoft.com/en-us/cli/azure/install-azure-cli)
and take note of the generated service principal's ID (also called _client ID_)
and password (also called _client secret_).
```yaml
name: ci
on:
push:
branches: main
jobs:
login:
runs-on: ubuntu-latest
steps:
-
name: Login to ACR
uses: docker/login-action@v3
with:
registry: <registry-name>.azurecr.io
username: ${{ vars.AZURE_CLIENT_ID }}
password: ${{ secrets.AZURE_CLIENT_SECRET }}
```
> Replace `<registry-name>` with the name of your registry.
### Google Container Registry (GCR)
> [Google Artifact Registry](#google-artifact-registry-gar) is the evolution of
> Google Container Registry. As a fully-managed service with support for both
> container images and non-container artifacts. If you currently use Google
> Container Registry, use the information [on this page](https://cloud.google.com/artifact-registry/docs/transition/transition-from-gcr)
> to learn about transitioning to Google Artifact Registry.
You can authenticate with workload identity federation or a service account.
#### Workload identity federation
Configure the workload identity federation for GitHub Actions in Google Cloud,
[see here](https://github.com/google-github-actions/auth#setting-up-workload-identity-federation).
Your service account must have permission to push to GCR. Use the
`google-github-actions/auth` action to authenticate using workload identity as
shown in the following example:
```yaml
name: ci
on:
push:
branches: main
jobs:
login:
runs-on: ubuntu-latest
steps:
-
name: Authenticate to Google Cloud
id: auth
uses: google-github-actions/auth@v1
with:
token_format: access_token
workload_identity_provider: <workload_identity_provider>
service_account: <service_account>
-
name: Login to GCR
uses: docker/login-action@v3
with:
registry: gcr.io
username: oauth2accesstoken
password: ${{ steps.auth.outputs.access_token }}
```
> Replace `<workload_identity_provider>` with configured workload identity
> provider. For steps to configure, [see here](https://github.com/google-github-actions/auth#setting-up-workload-identity-federation).
> Replace `<service_account>` with configured service account in workload
> identity provider which has access to push to GCR
#### Service account based authentication
Use a service account with permission to push to GCR and [configure access control](https://cloud.google.com/container-registry/docs/access-control).
Download the key for the service account as a JSON file. Save the contents of
the file [as a secret](https://docs.github.com/en/actions/configuring-and-managing-workflows/creating-and-storing-encrypted-secrets#creating-encrypted-secrets-for-a-repository)
named `GCR_JSON_KEY` in your GitHub repository. Set the username to `_json_key`.
```yaml
name: ci
on:
push:
branches: main
jobs:
login:
runs-on: ubuntu-latest
steps:
-
name: Login to GCR
uses: docker/login-action@v3
with:
registry: gcr.io
username: _json_key
password: ${{ secrets.GCR_JSON_KEY }}
```
### Google Artifact Registry (GAR)
You can authenticate with workload identity federation or a service account.
#### Workload identity federation
Your service account must have permission to push to GAR. Use the
`google-github-actions/auth` action to authenticate using workload identity as
shown in the following example:
```yaml
name: ci
on:
push:
branches: main
jobs:
login:
runs-on: ubuntu-latest
steps:
-
name: Authenticate to Google Cloud
id: auth
uses: google-github-actions/auth@v1
with:
token_format: access_token
workload_identity_provider: <workload_identity_provider>
service_account: <service_account>
-
name: Login to GAR
uses: docker/login-action@v3
with:
registry: <location>-docker.pkg.dev
username: oauth2accesstoken
password: ${{ steps.auth.outputs.access_token }}
```
> Replace `<workload_identity_provider>` with configured workload identity
> provider
> Replace `<service_account>` with configured service account in workload
> identity provider which has access to push to GCR
> Replace `<location>` with the regional or multi-regional [location](https://cloud.google.com/artifact-registry/docs/repo-organize#locations)
> of the repository where the image is stored.
#### Service account based authentication
Use a service account with permission to push to GAR and [configure access control](https://cloud.google.com/artifact-registry/docs/access-control).
Download the key for the service account as a JSON file. Save the contents of
the file [as a secret](https://docs.github.com/en/actions/configuring-and-managing-workflows/creating-and-storing-encrypted-secrets#creating-encrypted-secrets-for-a-repository)
named `GAR_JSON_KEY` in your GitHub repository. Set the username to `_json_key`,
or `_json_key_base64` if you use a base64-encoded key.
```yaml
name: ci
on:
push:
branches: main
jobs:
login:
runs-on: ubuntu-latest
steps:
-
name: Login to GAR
uses: docker/login-action@v3
with:
registry: <location>-docker.pkg.dev
username: _json_key
password: ${{ secrets.GAR_JSON_KEY }}
```
> Replace `<location>` with the regional or multi-regional [location](https://cloud.google.com/artifact-registry/docs/repo-organize#locations)
> of the repository where the image is stored.
### AWS Elastic Container Registry (ECR)
Use an IAM user with the ability to [push to ECR with `AmazonEC2ContainerRegistryPowerUser` managed policy for example](https://docs.aws.amazon.com/AmazonECR/latest/userguide/ecr_managed_policies.html#AmazonEC2ContainerRegistryPowerUser).
Download the access keys and save them as `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY` [as secrets](https://docs.github.com/en/actions/configuring-and-managing-workflows/creating-and-storing-encrypted-secrets#creating-encrypted-secrets-for-a-repository)
in your GitHub repo.
```yaml
name: ci
on:
push:
branches: main
jobs:
login:
runs-on: ubuntu-latest
steps:
-
name: Login to ECR
uses: docker/login-action@v3
with:
registry: <aws-account-number>.dkr.ecr.<region>.amazonaws.com
username: ${{ vars.AWS_ACCESS_KEY_ID }}
password: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
```
If you need to log in to Amazon ECR registries associated with other accounts,
you can use the `AWS_ACCOUNT_IDS` environment variable:
```yaml
name: ci
on:
push:
branches: main
jobs:
login:
runs-on: ubuntu-latest
steps:
-
name: Login to ECR
uses: docker/login-action@v3
with:
registry: <aws-account-number>.dkr.ecr.<region>.amazonaws.com
username: ${{ vars.AWS_ACCESS_KEY_ID }}
password: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
env:
AWS_ACCOUNT_IDS: 012345678910,023456789012
```
> Only available with [AWS CLI version 1](https://docs.aws.amazon.com/cli/latest/reference/ecr/get-login.html)
You can also use the [Configure AWS Credentials](https://github.com/aws-actions/configure-aws-credentials)
action in combination with this action:
```yaml
name: ci
on:
push:
branches: main
jobs:
login:
runs-on: ubuntu-latest
steps:
-
name: Configure AWS Credentials
uses: aws-actions/configure-aws-credentials@v4
with:
aws-access-key-id: ${{ vars.AWS_ACCESS_KEY_ID }}
aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
aws-region: <region>
-
name: Login to ECR
uses: docker/login-action@v3
with:
registry: <aws-account-number>.dkr.ecr.<region>.amazonaws.com
```
> Replace `<aws-account-number>` and `<region>` with their respective values.
### AWS Public Elastic Container Registry (ECR)
Use an IAM user with permission to push to ECR Public, for example using [managed policies](https://docs.aws.amazon.com/AmazonECR/latest/userguide/security-iam-awsmanpol.html#security-iam-awsmanpol-AmazonEC2ContainerRegistryPowerUser).
Download the access keys and save them as `AWS_ACCESS_KEY_ID` and
`AWS_SECRET_ACCESS_KEY` [secrets](https://docs.github.com/en/actions/configuring-and-managing-workflows/creating-and-storing-encrypted-secrets#creating-encrypted-secrets-for-a-repository)
in your GitHub repository.
```yaml
name: ci
on:
push:
branches: main
jobs:
login:
runs-on: ubuntu-latest
steps:
-
name: Login to Public ECR
uses: docker/login-action@v3
with:
registry: public.ecr.aws
username: ${{ vars.AWS_ACCESS_KEY_ID }}
password: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
env:
AWS_REGION: <region>
```
> Replace `<region>` with its respective value (default `us-east-1`).
### OCI Oracle Cloud Infrastructure Registry (OCIR)
To push into OCIR in specific tenancy the [username](https://www.oracle.com/webfolder/technetwork/tutorials/obe/oci/registry/index.html#LogintoOracleCloudInfrastructureRegistryfromtheDockerCLI)
must be placed in format `<tenancy>/<username>` (in case of federated tenancy use the format
`<tenancy-namespace>/oracleidentitycloudservice/<username>`).
For password [create an auth token](https://www.oracle.com/webfolder/technetwork/tutorials/obe/oci/registry/index.html#GetanAuthToken).
Save username and token [as a secrets](https://docs.github.com/en/actions/configuring-and-managing-workflows/creating-and-storing-encrypted-secrets#creating-encrypted-secrets-for-a-repository)
in your GitHub repo.
```yaml
name: ci
on:
push:
branches: main
jobs:
login:
runs-on: ubuntu-latest
steps:
-
name: Login to OCIR
uses: docker/login-action@v3
with:
registry: <region>.ocir.io
username: ${{ vars.OCI_USERNAME }}
password: ${{ secrets.OCI_TOKEN }}
```
> Replace `<region>` with their respective values from [availability regions](https://docs.cloud.oracle.com/iaas/Content/Registry/Concepts/registryprerequisites.htm#Availab)
### Quay.io
